i'm looking at mounting these in a long canopy on the underside of three 26" long flip up lids

if i do something like the following layout is there an extension cable to get me to the 3rd fixture?
(the drawing is not to scale, just something quick i threw togther for a quick layout/wiring diagram of the canopy

Hey, I personally don't know of a extension cable but you may be able to find it online. The 3 way splitters are actually fairly long. For longer fixtures, you will need to use multiple power supplies as well. One power supply can only support 60 watts at most but you want to keep it under 50 watts if you don'twant the power supply to burn out in less than a year.

exactly how long are the lines on the 3 way splitter? i guess i could always splice in some extra wire, but i'm trying to keep things as factory as possible.

as for power 3 of the 24" fixtures @ 16w for a total of 48w should be just about perfect. Its a narrow tank, and only about 16" to the substrate, so with a 120* light angle i should get a decent spread and the plants i'm working with on that tank will be fine with the par levels i'm expecting out of the fixtures. I'm EI style dosing and there's co2 supplementation on a pressurized tank. Tank currently consumes ~60ppm worth of no3 per week and is moderately to heavily stocked.

i've got side by side tek retrofit kits in there now running the full length (6x24") but the reflectors are 5+ years old. At this point with the bulb replacement coming up and the fact that my reflectors are showing their age, i think this is going to be a great long term jump forward for the tank and when i figure in the expected update cost of keeping my t5's rocking its going to offset the upgrade cost nicely
